A 47-year-old Middletown woman pleaded guilty last week to embezzling $349,000 from her employer over nearly a four-year period.

Kimberly Y. Drummond is facing a maximum sentence of 30 years in prison, a $1,000,000 fine and six years of supervised probation, according to the U.S. District Attorney Charles M. Oberly III’s office.

Her sentencing is scheduled for April 3 in the U.S. District Court of Delaware.

According to court documents, Drummond stole the money from Discover Financial Services in New Castle, where she worked for nearly 20 years.

Starting sometime in November 2008, Drummond began falsifying entries in Discover’s books and records, resulting in the issuance of duplicate checks from Discover Bank. Drummond then deposited those duplicate checks into her personal bank account, which she used to pay her mortgage lender through August of 2012.

The thefts were investigated by the Federal Bureau of Investigation, resulting in Drummond entering a guilty plea to one count of embezzlement from a federally-insured financial institution on Dec. 12.

“Yet another breach of trust by someone entrusted to protect financial resources,” Oberly said in a statement issued Monday. “These cases will be vigorously prosecuted by this office and appropriate punishment will be sought.”
